Question

A school library has books of different languages as depicted by the adjacent bar graph. Read the graph and answer the questions that follow:

How many Punjabi books are fewer than Hindi books?

Answer 1

From the bar graph, it is evident that the bar corresponding to the Hindi books touches the line that comes exactly between $300$ and $400$ books.

Since each small divisions between two large divisions in the graph represents $10$ books, the number of Hindi books is $350$.

Also, it is evident in the bar graph that the bar corresponding to the Punjabi language touches the line that represent $300$ books.

So, the difference between the Punjabi books and Hindi books

⇒ $350-300=50$

Hence, the number of Punjabi books fewer than Hindi books is $50$.
